Archai: Platform for Neural Architecture Search

Archai is a platform for Neural Network Search (NAS) that allows you to generate efficient deep networks for your applications. It offers the following advantages:

• 🔬 Easy mix-and-match between different algorithms;
• 📈 Self-documented hyper-parameters and fair comparison;
• ⚡ Extensible and modular to allow rapid experimentation;
• 📂 Powerful configuration system and easy-to-use tools.

Please refer to the documentation for more information.

Archai is compatible with: Python 3.6+ and PyTorch 1.2+.

Quickstart

Installation

There are many alternatives to installing Archai, ranging from PyPI to Docker. Feel free to choose your preferred, but note that regardless of choice, we recommend using it within a virtual environment, such as conda or pyenv.

Archai is compatible with Windows, Linux, and MacOS.

PyPI

PyPI provides a fantastic source of ready-to-go packages, and it is the easiest way to install a new package:

pip install archai

Source (development)

Alternatively, one can clone this repository and install the bleeding-edge version:

git clone https://github.com/microsoft/archai.git
cd archai
install.sh # on Windows, use install.bat

Please refer to the installation guide for more information.

Running Experiments

To run a specific NAS algorithm, specify it by the --algos switch:

python scripts/main.py --algos darts --full

Please refer to running algorithms for more information on available switches and algorithms.

Tutorials

The best way to familiarize yourself with Archai is to take a quick tour through our 30-minute tutorial. Additionally, one can dive into the Petridish tutorial developed at Microsoft Research and available at Archai.

Visual Studio Code

We highly recommend Visual Studio Code to take advantage of predefined run configurations and interactive debugging.

From the archai directory, launch Visual Studio Code. Select the Run button (Ctrl+Shift+D), choose the run configuration you want, and click on the Play icon.

AzureML Experiments

To run NAS experiments at scale, you can use Archai on Azure.
